A former Scouts leader who allegedly molested nine children while away on camps in NSW some 30 years ago has been hit with a third wave of charges.
The 58-year-old was previously charged in September 2016 for historical child sexual assault offences and remains before the court, police say.
Subsequently police received further allegations that two boys were assaulted while on trips around Lithgow, Sydney and Mount Pritchard between 1985 and 1989.
The man was bailed but arrested again in December 2016 and charged with a further five counts for gross indecency on a male under 18.
Detectives then received new information from a third victim alleging assaults taking place on camps in the Snowy Mountains and Mount Pritchard in 1988.
Police say the man was again arrested when he reported for bail at Campbelltown Police Station on Thursday morning.
He was charged with 21 counts of intercourse with a male over 10, some 15 counts of indecent assault on a person under authority and two counts of gross indecency on a male under 18.
In total, he now faces 85 charges relating to nine victims aged between seven and 16-years-old.
He was again released on strict bail conditions and is expected to appear in Campbelltown Local Court on Wednesday.
